11 claims.

This invention relates to articles of manufacture in which strips aresewed edgewise to sheets and is illustrated herein as exemplified by aninsole having strips so attached thereto as to provide ribs to which ashoe upper may be secured.

Objects of the invention are to provide articles of manufacturecomprising sheets having strips upstanding from the surfaces thereofvand more y particularly to provide inexpensive insoles for 1o shoeshaving strips projecting from the'surfaces thereof sufliciently toreceive a securing means E for attaching the uppers to the insolesduring the lasting operation.

In one aspect the invention consists in an f5" article of manufacturecomprising a sheet having a thin strip placed edgewise thereon and aline of stitching the stitches of whichV extend-through the strip fromedge to edge and through the sheet. In a, further aspect the inventioncomprises an insole having a strip projecting from the surface thereofsufciently to receive. the securing means for attaching an upper to theinsole during the lasting operation, said strip being secured totheinsole by stitches which eX- 5 tend through the insole and from edge toedge through the strip. As illustrated, one edge face of the strip maybe beveled to cause the strip to be inclined toward the median line ofthe insole.

These and other aspects of the invention will appear more fully from thefollowing description when read in connection with the accompanyingdrawing and will be pointed out in the appended claims.

In the drawing:-

Figure 1 is a plan of the top side of an insole with the attached uppersecuring strips according to the invention;

Figs. 2 and 2A are sections, on an enlarged scale, on the lines 2-2 and2A-2A respectively of. Fig. 1; Y

Fig. 2B illustrates an insole with a modified form of strip, andcorresponds to a section on the line 2 2 of Fig. 1;

Fig. 2C is a transverse cross-section of the strip according to Fig. 2Bbefore it is applied to the insole;

Figs. 3 and 4 are sections through the shoe and last, corresponding tothe sections on the line 2-2 of Fig. 1, illustrating steps performed inthe method of making the shoe;

Fig. 3A is a fragmentary section, corresponding to Fig. 3, showing themodified form of insole and strip according to Figs. 2B and 2C;

According to one form of the invention, the

insole I has secured thereto, at opposite sides (Cl. Sii-22) thereof,strips 3 of suitable material such as leather, or leather substitutesuch as paper compositions and the like, these strips being ofrelatively small size, for example, but without limitation thereto, inthe order of lg thick and from 1A; to le" high. If desired. the insolemay comprisey a heel and shank stifiener which as shown is in the formof a thin sheet 4 of fiber board or the like cemented or otherwisesecured to the main portion of the insole before applying the strips. Y

A As illustrated by Figs. 1, 2 and 3, the strips are of rectangularcross-section and are placed edgewise` against the insole and are sewedthereto` byv lines lof stitching 5, the stitches 1 of whichpreferably'passthroughvthe insole and from edge to edge .through thestrip. Bypthis construction rigid abutments are formed for enabling anupper 9 to be drawn over a last li and to be secured to the abutments bystaples or other securing means i3.

-In the form of the invention illustrated by Figs. 2B and 2C the strips3 are inclined inwardly from the edges of the insole, which constructionmay be desirable to facilitate the stapling operationV When employingcertain forms of stapling instrumentalities. For this purpose the edges8 of the strips contacting with the insole surface are beveled. Thestrips may be held normally to the insole during the sewing operationand when sewed the tension of the stitches acts .to draw the strips intotheir inclined positions illustrated.

Before the upper is Worked into lasted position and secured tothe strip3, forming the insole rib, for example, by staples or the like, cementmay be applied to the portion of the insole between its edges and thestrips 3, or to the corresponding portions of the uppers, or both, thestaples holding the uppers in place until the cement dries. Thiscementing operation may be facilitated, if desired, by subjecting topressure that portion of the uppers which overlaps the insole. After theuppers are cemented in position, as indicated in Figs. 3 and 3A, thestrips 3 and excess portions of the uppers may be severed by a trimmingoperation, leaving the shoe in the condition illustrated by Fig. 4preparatory to apply- Ving the sole. 'I'he method of utilizing my novelinsole may be substantially as described in Letters Patent of the UnitedStates No. 1,932,545, granted October 31, 1933, on an application ofGeorge Goddu.

It will be observed that the stitches passing through the stripsedgewise, being under tension and of considerable diameter relative tothe thickness of the strips, draw the latter tightly against the insoleto form a substantially rigid abutment, which eliminates all substantialtendency of the abutment to bend or tilt during the operation ofapplying the uppers. Thus is avoided the common defect of priorconstructions. Y

It will also be understood that the invention is not limited to insolesor shoes, but comprehends any construction in which a stripI is sewededgevvise to a sheet or other shape.

The machine for making my novel insole originally disclosed herein isbeing disclosed and claimed in the divisional application Serial No.97,839, filed August 25, 1936.

Having described the invention, what I claim as new and desire to secureby Letters Patent of the United States is:
